i say bring a lookout with you, throw their name up or wait until your done so you can be their lookout. but i think stopping while you're in the middle of the throw is the most idiotic thing on earth. if you're afraid of a random joe seeing you bombing, i don't think you're cut out to bomb.
it's kind of like bombing the highway, if someone sees you, chances are they're not going to stop, reverse with all that traffic behind them, get an accurate description of you then call the cops. gotta be logical. fast, in and out type shit.
